MUSICAL-INSTRUMENT VALVE.

Application filed August 14, 1917.

To all whom it may concern:

Be it known that I, ROBERT A. GALLY, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Musical- Instrument Valves, of which the following is a specification.

Rectangular valves or so called pallets are very old in pipe and reed organs, being used for the control of the ports to the pipes in the slide chest style of pipe organs, or the ordinary type of so called American reed organs, in such uses the valves being ordinarily made of blocks of wood of the full size of such valves and having soft leather facings, or leather facings backed w1th felt, these valves being lifted from their seats at one end only, or at both ends, and the springs for their return motion being either placed with the two arms of a double arm or pallet spring set with one arm against the wood of such valve or pallet, and the other arm against some other fixed part of the apparatus. Whenformer rectangular valves have been used for the pumpers or bellows they have usually been without any wood or other rigid part moving wlth the main valve part, the moving valve usually being of a leather sufficiently thick and firm to insure its holding from buckling in at the valve holes under heavy air tension, although in large valves for pipe organ bellows wooden guards are placed over the leather valves, and holding down one line of the leather yet allowing a free part of the leather to move to and rom the valve holes under the freely set part of the guard. Gircular valves with a rigid reinforcing disk centrally attached to the flexible valve material have been patented by this applicant 1n his Patent #1,103,754, July 14, 1914.

In the drawings Figure 1, is a plan view of the improved valve applied to a pumper, and Fig. 2 is an end view of the same pumper and valve.

The present shown valve consists of a yielding face piece 1 of leather or the like which is positioned over the ports 2 on the moving board 3 of the pumper of a bellows for a layer iano, the particular structure now s own lleing especially adapted for the high air tension and rapid operation of the pumpers for such instruments wh1ch are driven by electric motor or other power Specification of Letters Iatent.

means, as shown in applicants application #179, L14 filed July 9, 1917.

The ports 2 are disposed in a row and the valve face 1 extends over all these ports and sufficiently beyond the end ports and the sides of all the ports to insure a safe sealing against air leakage when said valve i seated. To prevent the buckling of valve face 1 a reinforcing strip 4 of wood or the like is attached lengthwise along the middle of the face 1 on its outer surface, such attaching preferably being made more certain, or done entirely by screws 5 inserted through the face 1 into the stiffener 4:. A deadening member 1 of felt or the like ma be inserted between the face 1 and the sti ener 4 to lessen any thump when the valve returns to its seat.

At each end of the stiflener 4 is a slot 6 which slot 6 guides the stiffener 4 to osition with the ports 2 by means of the guide pins 7. These guide pins 7 have their upper art bent into an angle hook or dag 8 extending over the stiffener but sufiiciently above the said stiffener to allow of the ends of a spring 9 extending between the stiffener and the dag 8 and also allow for a proper amount of motion of the valve, the dags 8 acting as checks to said motion, and the extent of such motion can be regulated by making the attached ends of the pins 7 with screw threads where these pins enter the pumper board 3. Such screw threaded attachment of the pins 7 and their dags 8 enable the easy removal of a valve by giving the dag and pin a half turn.

Thespring 9 extends a little less than the length between the inner ends of the two slots 5 of the stiffener 4, so that this spring will never rub against either of the p1ns 7. The middle part of the spring 9 is attached to that part of the stiffener 1, and each end of the spring 9 may be slightly bent or curved upwardly to clear the stiffener and allow motion of the stiffener and the valve, or the stiffener 4 may be coved out or tapered to gain such clearance, or both the bending and the clearin of the stiffener be combined. Deadening elts are preferably employed above and below the end of the spring 9 to avoid any checking noises during the movement of the valve.

To insure greatest possible strength around the edges of the ports 2 and between the said ports, and also gain a free and quiet flow of air through the said ports 2, both the upper and lower entries of these are tapered inward from each face of the pumper board 2 but these tapers preferably not meeting at the middle of the board, but at sufficiently less than that point to leave a moderate distance of a straight hole.

By the present structure a very light, quick acting, quiet, and efiicient valve is ob tained.

What I claim as my invention is 1. In combination: an oblong rectangular valve having a face member and a stiffener member attached to the said face member along the middle and lengthwise of the said face member and on the outer surface of the said face member, said stiffener member being substantially less in width than said face member.

2. In combination: a bodily movableoblong rectangular valve having a face member and a stiffener member attached to the said face member along the middle and lengthwise of the said face member and on the outer surface of the said face member, said stiffener member being substantially less in width than said face member.

3, In combination: an oblong rectan ular valve having a face member and a sti 'ener member attached to the said face member along the middle and lengthwise of the said face member and on the outer surface of the said face member, said stifiener member being substantially less in width than said face member; a spring attached midway the outer face of said stiflener member and free from said stilfener member at the ends of said spring and member, a valve seat, and fixed members attached to the said valve seat and extended to positions opposite the outer ends of the said spring, the said outer ends of said spring standing between the said stiffener and the said fixed members.

4. In combination: a bodily movable oblong rectangular valve having a face memher and a stiffener member attached to the said face member along the middle and lengthwise of the said face member and on the outer surface of the said face member, said stiffener member being substantially less in Width than said face member, an oblong narrow strip form spring extended in the same general direction as the general direction of the length of the said stiffener and attached midway the outer ,face of said stiffener member and free from said stiffener member at the ends of said spring and member, a valve seat and fixed members attached to the said valve seat and extended to positions opposite the outer ends of the said spring, the saidouter ends of said springs standing between the said stiffener and the said fixed members.

5. In combination: an oblong rectan 'ular valve having a face member and a sti 'ener member attached to the said face member lengthwise of the said face member and 011 the outer surface of thesaid face member, a spring attached midway the outer face of said stiffener member and free from said stifl'ener member at the ends of said spring and member, a valve seat, and fixed members attached to the said valve seat and extended to positions opposite the outer ends of the said spring, the said outer ends of said spring standing between the said stiffener and the said fixed members;

6. In combination: a bodily movable oblong rectangular valve having a face member and a stiffener member attached to the said face member lengthwise of the said face member and on the outer surface of the said face member, an oblong narrow strip form spring extended in the same general direction as the general direction of the length of the said stiffener and attached midway the outer face of said stiflenermemher and free from said stiffener member at the ends of said spring and member, a valve seat, and fixed members attached to the said valve seat and extended to positions opposite the outer ends of the said spring, the said outer ends of said springs standing between the said stiffener and the said fixed members.
